Neuroendocrine regulation and behavior

This study examines how intranasal oxytocin affects brain entropy in young and old adults using fMRI-based mapping and finds age-dependent changes in brain activity.

This study introduces an automated two-choice social operant task to investigate moment-to-moment social satiety in animals, finding that males exhibit behavioral signatures of satiety and sensitivity to interaction duration.

This study shows that knocking down oxytocin receptors in specific brain regions of female mice reduces stress-induced social avoidance behaviors.

This study investigates how erratic maternal care in mice affects attachment-like behavior, finding avoidant-like deficits in some tests but not others.

The paper shows how hunger and estrous state interact in the MPOA to regulate infant-directed aggression in mice.

The paper identifies a neural circuit in female mice that transiently becomes active during lactation, enabling maternal aggression through hormonal regulation.

The paper shows that opioid receptor antagonists increase social conditioned place preference in early adolescent mice, suggesting developmental changes in social motivation mechanisms.

This study investigates how oxytocin affects hyperaltruistic preferences in moral decision-making contexts, showing it restores context-dependent preferences by altering subjective harm framing.

This study shows oxytocin signaling in pups affects vocal behavior during maternal separation and reunion, with sex-specific effects when oxytocin neurons are silenced.

The paper examines circadian variation in salivary oxytocin levels in young adult women, finding a significant increase between awakening and early afternoon with no group differences or interaction.

This study shows that hypothalamic Agrp neurons regulate age-specific sociability, with their activity critical for social behavior during adolescence but not adulthood.

The paper examines sex differences in mRNA expression of PNN-associated proteins and receptors in the vACC during pair bond formation in California mice, revealing sex-specific plasticity patterns.

The paper maps oxytocin and dopamine receptor expression in prairie and meadow voles to understand their role in pair bonding.

This study shows testosterone affects agonistic behavior differently in prepubertal and adult male Syrian hamsters, increasing attacks and dominance in prepubertal males and flank marking in adults.

This study shows that the orbitofrontal cortex promotes alloparental caregiving in female mice by modulating dopamine dynamics during behavior acquisition.

This study shows that juvenile mice retain strong maternal preference post-weaning, which remains resilient to immune activation, with sex-specific differences in exploration behavior.

This study shows that sociability and social hierarchy are genetically separable in amniotes through PAS1 mutations in mice and wallabies/chickens.

The paper identifies sex-biased gene expression in the juvenile rat medial amygdala associated with playfulness, showing inhibitory neurons drive this difference.

The paper shows that oxytocin receptor-expressing BNST neurons are excited by AVP and OT inputs, reducing anxious arousal and threat avoidance.

This study examines social hierarchy formation in sex-changing fish, finding that dominance is size-based and disruption leads to rapid behavioral and neural changes.

The paper builds a cellular atlas of the hypothalamic preoptic area in two deer mouse species, identifying cell types linked to behavioral differences and sex-specific evolution.

This study investigates how oxytocin and its antagonist affect risky decision-making in male and female rats, finding sex-dependent effects on reward preference.

The paper examines sex steroid receptor expression in Otp glutamatergic neurons of the medial extended amygdala and finds sex differences in receptor expression and neuronal morphology.

This study shows oxytocin regulates blood flow and permeability in the neurohypophyseal system to enhance its own uptake into the bloodstream.

The paper investigates how early social experience in fish affects neuroplasticity markers in brain regions related to social decision-making.

This study examines AVPR1a and OXTR receptor densities in schizophrenia patients and controls, finding age- and sex-dependent changes in the superior temporal sulcus and hypothalamus.

The paper identifies hypothalamic neurons that promote social behavior after short-term isolation, showing sex- and context-dependent effects.

Opposing glutamatergic MPN Isolation and mostly GABAergic MPN Reunion neurons in the mouse preoptic hypothalamus encode social need and satiety, with touch as a likely cue.

This study shows that oxytocin enhances trust acquisition in male mice but blocks trust violation learning, while its antagonist has similar effects, with no impact on females.
